Control使用CSS，Javascript和Anchor显示/隐藏多个DIV，而不使用唯一ID

I have an older JavaScript/CSS file that used to (no longer works in current browsers) toggle the display properties for multiple divs by way of anchor tags. The CSS document.stylesheets would toggle based on value "rules", that required the style to be in a specific sequence to control the "none" to "block" toggling (or the reverse). Here is a link to the JSFiddle example: JSFiddle

我有一个旧的JavaScript / CSS文件,以前(不再适用于当前浏览器)通过锚标记切换多个div的显示属性。 CSS document.stylesheets将根据值“规则”进行切换,这需要样式按特定顺序控制“无”到“阻止”切换(或反向)。这是JSFiddle示例的链接:JSFiddle

Here is the JavaScript:

这是JavaScript:

function NorB(arg){
if (arg=="n") {
    document.styleSheets[0].rules[0].style.display=='block';
    document.styleSheets[0].rules[1].style.display=='none';
} else {
    document.styleSheets[0].rules[0].style.display=='none';
    document.styleSheets[0].rules[1].style.display=='block';
}

}

Here is the HTML:

这是HTML:

    <table>
    <tr>
    <td>
    <div class="narrative" id="rpmAct1">
        <div class="buttons">
            <div class="narButton"><a href="javascript: onClick=NorB('n')">Narrative ></a></div>
            <div class="bulButton"><a href="javascript: onClick=NorB('b')">List View ></a></div>
        </div>

        <div class="narrativeContent">
            <div class="n">Narrative text</div>
            <div class="b">
                <ul>
                    <li>List Item A</li>
                    <li>List Item B</li>
                    <li>List ITem C</li>
                </ul>
            </div>
        </div>  
    </div>
    </td>                   
    </tr>

    <tr>
    <td>
    <div class="narrative" id="rpmAct2">
        <div class="buttons">
            <div class="narButton"><a href="javascript: onClick=NorB('n')">Narrative 2></a></div>
            <div class="bulButton"><a href="javascript: onClick=NorB('b')">List View 2></a></div>
        </div>

        <div class="narrativeContent">
            <div class="n">Narrative 2 text</div>
            <div class="b">
                <ul>
                    <li>List 2 Item A</li>
                    <li>List 2 Item B</li>
                    <li>List 2 ITem C</li>
                </ul>
            </div>
        </div>  
    </div>
    </td>                   
    </tr>

</table>

And lastly, the CSS:

最后,CSS:

        .n {
        display:block;
    }
    .b {
        display:none;
    }
    .b ul {
        margin-left:3px;
        margin-top:0px;
        margin-right:10px;
        margin-bottom:-2px;
    }
    .b ul li {
        list-style-type:square;
        list-style-position:outside;
        line-height:12px;
    }
    .buttons {
        position:relative;
        width:300px;
    }
    .narButton {
        width:80px;
        float:left;
        padding:2px 0px 2px 5px;    
    }
    .bulButton {
        width:80px;
        float:left;
        padding:2px 0px 2px 5px;
    }
    .bulButton a, .narButton a {
        font-size:14px;
        font-style:normal;
        text-decoration:none;
    }
    .narrativeContent {
        border-top:1px solid #CCC;
        border-bottom:1px solid #CCC;
        padding:5px;
    }

Since there is a large number of div/anchor elements on the page, the goal is to avoid creating unique IDs for each, and continue to use basic CSS/JavaScript (avoid using jQuery and the like). Thoughts on how to keep this simple?

由于页面上有大量的div / anchor元素,目标是避免为每个元素创建唯一的ID,并继续使用基本的CSS / JavaScript(避免使用jQuery等)。关于如何保持这个简单的想法?

Append these CSS

附加这些CSS

.b-mode .b, .n-mode.n {
    display:block;
}
.b-mode .n, .n-mode.b {
    display:none;
}

Modify onclick action

修改onclick操作

<a href="#" onclick="NorB(this,'n')">

Modify Javascript

function NorB(e, arg) {
    var wrapper = e.parents('.narrative');
    var rm = arg == 'n' ? 'b' : 'n';
    wrapper.classList.add(arg + '-mode');
    wrapper.classList.remove(rm + '-mode');
}
Object.prototype.parents = function (selector) {
    if (selector.length == 0) return;
    var prefix = selector.substr(0, 1);
    if (prefix != '#' && prefix != '.') return;
    var selector = selector.substr(1);
    var p = this.parentNode;
    while (p !== null) {
        switch (prefix) {
            case "#":
                if (p.getAttribute('id') == selector) return p;
                break;
            case ".":
                if (p.classList.contains(selector)) return p;
                break;
        }
        p = p.parentNode;
    }
    return null;
};

Parfait's script is exactly what was needed:

Parfa的脚本正是所需要的:

function NorB(e, arg) {
    var wrapper = e.parents('.narrative');
    var rm = arg == 'n' ? 'b' : 'n';
    wrapper.classList.add(arg + '-mode');
    wrapper.classList.remove(rm + '-mode');
}
Object.prototype.parents = function (selector) {
    if (selector.length == 0) return;
    var prefix = selector.substr(0, 1);
    if (prefix != '#' && prefix != '.') return;
    var selector = selector.substr(1);
    var p = this.parentNode;
    while (p !== null) {
        switch (prefix) {
            case "#":
                if (p.getAttribute('id') == selector) return p;
                break;
            case ".":
                if (p.classList.contains(selector)) return p;
                break;
        }
        p = p.parentNode;
    }
    return null;
};
